METHOD OF PRODUCING MIATRICES.

To all whom it may concern:

Be it known that 1, WILLIAM H. KAISER, a citizen of the United States, residing at Floral Park, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Methods of Producing Matrices, of which the following is a specification, reference being had therein to the accompanying drawin My invention relates to the manufacture of matrices, such as are used in the commercial linotype machine, consisting of plates :ontaining in their edges intaglio characters, of matrices proper, from which the type characters are produced. These matrix characters are formed by a hardened steel punch having a formative surface which is an exact replica of the type character to be cast from the matrix. Ordinarily, each matrix plate contains a whole character, but in some cases it is found desirable to place complementary portions of a single character upon separate plates, such, for instance, as the large characters which are used in display work and the like. in pro ducing these latter matrices, it has been the practice to provide separate and distinct punches having complementary portions of the formative surface, each punch being used independently to act upon an individual matrix body, and following the regular course of manufacture of the ordinary matrices. This practice is objectionable, as it not only involves considerable expense and loss of time, but, in addition, it is difficult to secure the exact registration of the complementary portions of the matrix character upon the separate plates, owing to the great precision which must be observed in making the punches and mounting them in the machine for operation. Furthermore, it is found that the matrix plates often fail to lock up tightly against one another when assembled in line, owing to the irregularity of their adjacent side faces due to the flowing or displacement of the metal in the independent punching operations. As a result, the type characters produced from the matrices are sometimes distorted or show a distinct break, thus resulting in a bad or imperfect print. I

It is the object of my present invention to avoid the above objections, and to this end I propose to produce the large matrix characters by subjecting a plurality of matrix Specification of Letters Patent.

bodies to the action of an integral punch having a whole or single formative surface, whereby the complementary portions of the matrix clmractcr will be formed in the separate matrix bodies simultaneously and by a single operation.

While in the acompanying drawing 1 have sh on my invention as designed for the produc'tion of matrices with intaglio characters,

it will be understood that it may also be employed for the production of type or dies with cameo characters, this result merely involving a corresponding change of the formative surface of the punch.

Referring to the drawing: i igure 1 is a perspect've view of two blanks from which the complementar matrix sections are to be produced; Fig. 2 is a similar view showing the blanks assembled side by side in condition to be acted upon by the punch; Fig. 3 shows the matrix blanks properly supported in the press and undergoing the action of the puncn; Fig. iis a pers iective view of the finished matrix; Fig. 5 is a similar view showing the complementary sections separated; Pig. (3 shows the matrices assembled in a composed line; and Fig. 7 shows three complementary matrix sec tions, instead of two as in the foregoing figures.

The matrix, which it is the object of my invention to produce, is shown in finished form in l and 5, and comprises two complementary sections A and A containing in their adjacent edges the intaglio character or matrix proper B, one portion of which is located upon the section A and the other upon the section A produced from the blanks or bodies C and D shown in Figs. 1 and 2, which are adapted, to be assembled side by side upon the supporting plate E of the ordinary punch press and clamped tightly side by side between the j aws E and F with their edges exposed. When in this position, as shown in Fig. 3, the blanks are subjected to the action of an integral punch G carried by the reciprocating plunger H and having in its end. a: formative surface G corresponding to the particular character it is designed to produce. As the punch embeds itself in the matrix bodies, the displaced metal will flow from their outer faces into the usual cavities or recesses E and F of the jaws E and F respectively, the inner faces of the matrix This matrix is Cit bodies being held in close and firm contact with each other, thus avoiding any liability to distortion due to the punching action. As a result of this arrangement, the desired matrix character will be punched in a plurality of complementary matrix bodies simultaneously and by the employment of a punch having a whole or single formative surface. In this way, when the finished matrix is assembled in line, as shown in Fig. (3, its complementary sections will lie flatly against one another and locate the different portions of the matrix character in exact registration, so that the type character cast therefrom will present no breaks 01' irregularities.

In Fig. 7, the matrix character B is shown as being divided among three complementary sections J, J and J The production of such a matrix may be effected in exactly the same manner as above described, except that three matrix blanks should be subjected to the action of the punch instead of two.

The foregoing method and apparatus have been selected merely by way of example and as the preferred mode of procedure, but it will be understood that many changes and variations may be made therein without departure from the scope of my invention.

Generally speaking, I desire it to be understood that I do not limit myself to any particular procedure or arrangement, except in So far as such limitations are specilied in the claims.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:

1. The method of producing matrices which consists in assembling a pluralityof matrix bodies side by side in a suitable support, holding said matrix bodies together with their adjacent faces in firm contact with each other, and subjecting the'several matrix bodies simultaneously to a punching action.

2. The method of producing matrices which consists in assemblinga plurality of matrix bodies side by side in a suitable support, holding said matrix bodies together with their adjacent faces in firm contact with each other, and subjecting the several matrix bodies to the action ofa single integral punch.

The method of producing matrices which consists in assembling a plurality of matrix bodies side by side in a suitable support with their edges exposed, holding said matrix bodies firmly together by a pair of clamping aws formed with relief cavities in their active or engaging faces, and subjecting the several matrix bodies simultaneously to a punching action; whereby the metal displaced by the punching action will flow into the relief cavities of the clamping jaws and away from the region of contact between the matrix bodies.

4. The method of producing matrices, which consists in assembling a plurality of matrix bodies side by side in a suitable support with their edges exposed, applying a clamping pressure to thematrix bodies to hold their adjacent faces in firm contact with each other, and punching a single character in the exposed edges of the matrix bodies.

In testimony whereof, I have affixed my signature in presence of two witnesses.
